Application led March 4, 1916.

To all whom t may concern:

Be it known that I, WILLIAM C. MUNDORF, a citizen of the United States,residing at York, in the county of York and State Of Pennsylvania, haveinvented a certain new and useful Antiskid Device for VehiclelVheels, ofwhich the following is a specification.

This invention relates, generally to anti skid devices for vehiclewheels, and particularly to the means forsecuriug suoli devices to thespokes of automobile wheels, and it has for its object to provide afastening for such devices for attaching the same to vehicle wheels, offew parts, great strength and durability and comparatively inexpensive,it consists of the parts and combinations hereinafter described andclaimed.

In the accompanying drawings forming a part of this specification,

Figure 1 is a side elevation of a portion of an automobile wheel showingmy invention in position thereon.

Fig. 2 is a vertical transverse section of aA wheel showing theinvention in place.

Fig. 3 is a plan view of the clamp.

Fig. et is a perspective view of the clamp.

Similar numerals refer to similar parts in all the views.

Referring to the drawings the numeral 2 represents the felly of thewheel, 3 the rim, preferably of the clencher type; 4 a solid rubbertire, although the tire may be of pneumatic type if preferred. A spoke 5is also shown in Figs. 1 and The parts just described may be of theusual type, or any preferred suitable type, may be employed. Theanti-skid chain 6 is formed of twisted links, with the exception of theend links 7 which, as shown, are straight links, for a purpose whichwill be hereinafter described.

The chain 6 is of the individual or single type and is not designed tobe connected with its mates on the wheel.

For each chain used, a clamp is attached to one of the spokes of thewheel, said clamp consisting of two like or similar parts or halves 8,each of which is centrally curved outwardly to provide a eoncavity 9 toadapt it to t the curve of the spoke, said concavity Specification ofLetters Patent.

heilig provided with a lining 10 of any suitable material to prevent thedefacing of the painted spoke to which it is attached and to increasethe frietional adherence thereto of the clamp without injuring ormarring the spoke in adjusting the clamp thereto. Said halves 8 are alsoformed with a shoulder 11 at each side or end of the concavity throughwhich a bolt opening 19J is formed to receive a winged bolt 13 which issecured in position by a nut lll, thus locking the parts or halves 8together and to the spoke and permitting of the adjustment thereof onthe spoke. A lock washer 15 is interposed between the winged bolt headand the clamp.

The outer ends of the halves 8 are reduced in thickness relative to thethickness of the material at the shoulder l1, thus providing a space 16at each end which forms a clevis to receive the end links 7 of thechain, each of said parts havin@V an opening 19 to receive the headedpin 1I which is secured therein by a cotter pin 18, said pins 18 passingthrough the links 7 and holding the same securely in position.

It will be observed that any number of clamps may be employed, thenumber to be used being limited only by the number of spokes; and thateach chain extends directly across the tire and is so secured as torender it almost impossible for the same to become accidentally detachedor to work slack on the tire.

I am aware that it has been proposed to form a two part clamp with ahook at one end for one end of the chain. Such an arrangement, however,is a great disadvantage in adjusting the chain to secure the propertension on the tire and if it is slack on the tire, it injuriouslyaffects the same, while it greatly interferes with the efficiency of thechain as an anti-skid.

Having thus described my invention what I claim is: Y

A clamp comprising two like members each having a central concavity toreceive the element clamped, a shoulder upon opposite sides of saidconcavity forming abuttino surfaces when the clampis in position, andDreduced portions beyond. said lshoulders to form spaces between the endsof said members upon opposite sides of the clamp, Clamping bolts passingthrough the shouldered portions of said members for securing the membersof the clamp in clamping po-v sad spaced ends of the members to theclamp.

In testimony whereof, I zLIX my signiq Lure, in the presence of twoWitnesses.
